LG VX-8300

MP3 player help!!!

i just got the 8300 and before i start using my own microsd card for music i tried to use my sisters 512MB micro sd. when i put the card in my phonethe pictures from her card would show up, but none of hwer mp3's would show up. in other words how do i get the mp3 player to work when it gives me the message "PHONE ERROR" or "NO FILES FOUND". if anyone can help me with this problem it would be greatly appreciated.

Because of the silly Verizon music service they by default only allow wma files to play on the phone, so Mp3's will not be recognized. To turn on Mp3 abilities you must press menu, 0, 000000, and go to number 11 Music Setting and choose Mp3 Enable.
